SIPEGIFIGATION forming part of Letters Patent No. 686,290, dated November 12, 1901.

Application filed March 5,1901. Serial No. 49,683. (No model.)

To ctZZ whom, it may concern:

Be it known that I, MIGHEAL F. HAMMOND, a citizen of the United States, residing at Throop, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in the common form of miners lamps, which are usually constructed by soldering a long wickholding spout to a small tin can containing oil and are designed to be attached to the hats of working miners in workings Where an open flame is permissible; and the objects of the invention are to provide a device for directin g the flame upward, to prevent the flame from melting the solder of the parts, and to improve the efficiency of such lamps in general. The soldered portions of lamps of this class, especially the spout, are frequently melted off in consequence of the flame striking downward over the wick-tube, and many forms of protection have been resorted to in the way of adding double thicknesses to the tubes and constructing from a single piece and other devices entailing considerable expense without very satisfactory results. I

have discovered a very simple and effective method of meeting this diificulty; and my invention consists of the arrangement and construction of the parts herein specified, and illustrated in the drawings, in which-- Figure 1 is a side elevation showing a common form of miners lamp constructed with my improvement incorporated as a part of it. Fig. 2 is a rear view of the spout of the device, taken at right angles to that of Fig. 1. Fig. 3 shows a form for making the deflector used in my device, adapting it to be attached to lamps already made.

In the drawings, 1 designates the wickholding spout of an ordinary miners lamp soldered to the body of the lamp at the seam 2, the spout 1 being made from a single piece of tin closed together by a seam 3. When my improvement is to be incorporated during the manufacture of such lamps, I prefer to have a deflector 5, which is attached to the upper end of the wick-tube, secured into the Said seam 3 by means of a lug or flap 4:, which is tightly folded into the seam. If, however, it is designed to attach my improvement to lamps already made, then the deflector 5, which constitutes the principal feature of my invention, may be constructed with a loop or ring 4:, which is designed to encircle and clasp the upper end of the wick-tube 1, so that the deflector will occupy a position in proximity to the flame and in a plane passing through the middle of it. A deflector of this kind attached to the tube constitutes the essential feature of my invention. It may be attached in various ways and may be varied in size or differently located; but I prefer to attach it near to the top of the wick-tube and having a corner or other portion 6 extending slightly into the flame, for the reason that thus the deflector itself becomes thoroughly heated and becomes more efticient.

The operation of the device is more fully explained as follows: The deflector 5 becomes thoroughly heated by the flame of the lamp and radiates the heat to the contiguous atmosphere, thus causing an upward current of air on either side of the deflector, as indicated by the arrows. In ordinary lamps when the miner raises his head the flame flashes downward onto the spout; but with my deflector attached the upward current of air generated on either side of it is sufflcient to counteract the tendency for throwing the flame downward over the spout in raising the head or any other upward or forward motions of the lamp, thus completely obviating the former difficulty caused by having the flame sweeping downward over the wick-tube.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with a miners lamp, a flamedeflector constructed from a piece of flat metal, the said piece being secured to the upper end of the wick-tube so as to extend radially therefrom, and having one ed go thereof extending into the flame, substantially as and for the purpose specified.

2. In a sloping wick-tu be for miners lamps, a flame-deflector constructed from an angular piece of metal, one corner thereof extending into the flame, and the main part thereof extending radially from the flame in the direction of the sloping tube, but extending above the level of the top of the tube, substantially as and for the purpose specified.

3. As a new article of manufacture, the herein-described flame-deflector constructed from flat metal, and provided with means for attachment to the sloping tube of a miners lamp, adapted to be attached to the upper end thereof, having a portion thereof extend ing into the flame, and the main part thereof extending radially from the flame in the direction of the attachment of the tube to the lamp, for the purpose specified.
